The latest DIY ideas, techniques and tools for the manufacture of metal, wood, plastic, ceramic and composites. We talk about machining, using a lathe to machine metals like steel, brass, and aluminium. We make chips fly!
Three-jaw chucks, of the same general type used to hold bits in most power drills, are also common equipment on metalworking lathes. Though it is not necessarily so, three-jaw chucks are so commonly of the self-centering variety, in which the jaws are not independently adjustable, that “self-centering” is generally assumed from the term “three-jaw chuck.” But…
Quick, now: What are the two most fundamental measurements of the capacity of a metalworking lathe? If you said…
Back in Plastics Month, we featured a simple shop-made plastics extruder built by Instructables user Random_Canadian. Now the arbitrary Canuck returns with this pint-sized metal lathe built with a 14″ piece of precision aluminum T-slot extrusion, and some characteristically resourceful salvage including an electric motor from a cordless weed trimmer, a variable speed switch from a cordless drill, and a tailstock center improvised from a countersink.
Scares off wildlife, starts campfires, melts ice, burns weeds, and works wonders on nose hair. What could possibly go wrong? The grip is built up from laminated laser-cut 1/8″ ply. Nice design from Instructables user PDRWLSN.
The Brothers Brick has technical details, and a brief interview with builder Nick Jensen about why and how. The “Sniper Rifle System 99 Anti-Matériel” is Nick’s 10th full-size replica weapon, from the Halo universe, built entirely from Lego elements.
I set out to write a generic “props” round-up, but quickly discovered that our props tag is pretty deep, and covers a wide range of subjects including haunt props and/or prop furniture, elaborate costumes, and display props. I narrowed my focus, then, to props a person might carry around as part of a costume, and found, even then, there was more cool stuff than I could fit into one roundup.
From user Douglas Desrochers. The barrels appear to be PVC. They rotate around a piece of 1/2″ copper pipe, and a high-intensity LED is positioned to shine down the top one, strobing as the barrels spin. The whole thing is driven by the motor and battery pack from a cheap cordless drill. Let the Predator jokes commence.
